DETAILED DESCRIPTION

Clear Platform

Typical prior art platforms are opaque and an operator cannot seethrough them. If the platform is being used in a tight space or theoperator needs to see what is just outside the platform, the clearplatform increases the operator's visibility of his surroundings. When aplatform is opaque there is an increased probability of the operatorstriking an object with the platform because of reduced visibility.

Referring now to the drawings in general, the illustrations are for thepurpose of describing a preferred embodiment of the invention and arenot intended to limit the invention thereto.

The invention is directed to elevating platforms with walls, panels,knee spaces, floors, doors and combinations thereof made of clear ortransparent and/or translucent materials to provide high visibility tothe operator. The platform is constructed using optically clear ortranslucent materials, either in strategic locations or having anentirely clear platform, thereby giving the operator enhanced visibilityaround the platform, resulting in better performance. The presentinvention also increases operator safety and extends the life ofplatforms by making it easier for the operator to avoid running theplatform into objects.

The present invention provides for different combinations of materialsto achieve the enhanced visibility. Some example configurations are asfollows: Using a standard, opaque fiberglass platform, generallydescribed as 100 in FIG. 1 , sections of one or more walls are cut outand a clear, transparent panel 110 or panels are attached. The clearreplacement section is a planar shape or an outwardly bulbous shape 120which provides space for the knees of a squatting operator. In anotherconfiguration, the platform door is constructed of clear material. Inyet another configuration, the platform is constructed in the typicalfashion, but a resin system with a reflectance and refractive indexsimilar to glass is used, yielding an entirely clear platform withsimilar image displacement as glass (FIG. 2 ).

The clear materials are attached to a typical fiberglass platform byadhesive bonding, mechanical fastening, and combinations thereof. If thefiberglass platform is made to be clear, a resin is chosen to match thereflectance and refractive index of the glass, resulting in a compositelaminate that is optically clear and with similar image displacement asglass. The clear material has a refractive index of between about 1.3and 1.7, a reflectance between about 70 and 100, negligible scatteringand negligible absorbance.

For translucent designs, the translucent material is preferably betweenabout 30% and about 70% light transmission. More preferably, the % lighttransmission is about 40-60%. In another embodiment, the % lighttransmission is about 50%. An example preferred embodiment is whitepolycarbonate with a % light transmission of between about 30% and about70%. The make and model of an example preferred white translucentpolycarbonate is Sabic Lexan XL102UV.

Alternatively, a fiber reinforced thermoset resin with a clear gel coatmay be used to produce an entirely translucent platform structure.Translucent components such as panels, knee spaces, and doors could thenbe attached to the translucent platform structure. These translucentcomponents may be made from Polycarbonate, Acrylic, Nylon,Polypropylene, fiber reinforced thermosets, and unreinforced thermosets.

Alternatively, polycarbonate, acrylic, nylon, polypropylene,fiber-reinforced thermosets, and unreinforced thermosets may be used toproduce an entirely translucent platform.

In another alternative embodiment, a platform structure is made withfiberglass, an optically clear thermoset resin, and a translucent gelcoat to allow light transmission but maintain privacy.

Alternatively, a reinforced thermoplastic such as Vectorply EPP-W 1500or Vectorply EPP-W 2200 may be used to create an entire platform orplatform components such as a panel, knee space, or door. The Vectorplyproducts are a fiberglass reinforced polypropylene and they becometranslucent after they are processed during manufacturing of platformsand platform components.

In a preferred embodiment, the resins are acrylic-modified resins suchas POLYLITE 32030-00 and 32030-10, manufactured by REICHHOLD, ResearchTriangle Park, N.C., USA. In one embodiment, the acrylic-modified resinsinclude polyester resins. Preferably, the acrylic-modified resins arelow-viscosity resins, low-reactivity resins, and UV-stabilized resins.Any clear or translucent thermoplastic or thermoset, impact-resistantpolymer, such as polycarbonate, can be used without departing from thescope of the invention.

The invention is thus directed to an elevating platform with at leastone wall; and further including at least one panel, at least one kneespace, and/or at least one door. The at least one wall, the at least onepanel, the at least one knee space, and/or the at least one door isformed of a clear or translucent material, thereby providing anelevating platform which provides for greater visibility to an operator.In another embodiment, the elevating platform includes at least oneclear or translucent section in the at least one wall, wherein theremainder of the at least one wall is constructed out of a differentmaterial than the at least one clear or translucent section. The atleast one clear or translucent section is attached to the elevatingplatform by adhesive bonding and/or mechanical fastening. The at leastone clear or translucent section is a planar shape or a knee spaceformed by an outwardly bulbous shape using clear or translucentmaterial. The knee space provides space for at least one knee of asquatting operator. In another embodiment, the entire elevating platformis constructed using fiberglass and a clear or translucent resin systemsuch that the elevating platform is entirely clear or translucent. Theclear resin system has a refractive index between about 1.3 and about1.7. The translucent resin system has a % light transmission of betweenabout 30% and about 70%. The clear or translucent material isfiber-reinforced thermosets, unreinforced thermosets, fiber-reinforcedthermoplastics, and/or unreinforced thermoplastics. The translucentresin system is preferably white polycarbonate.

Platform Step

The present invention is further directed to a step for use in elevatingplatforms. Steps are located on the sidewall of a platform, and theoperator uses them as an aid to get into and out of the platform.Typical prior art steps have a flange all around the step that is bondedto the outside of the platform wall (FIG. 3A). When a load is applied tothe step (e.g. an operator stands on it), the bondline on the upperportion of the step flange is in tension (step is trying to pull awayfrom the platform wall). The bondline on the lower portion of the stepflange is in compression (trying to push into the platform wall).Failures typically initiate on the portion of the bondline that is intension, and not on the portion of the bondline in compression.

In an alternative prior art embodiment (FIG. 3B), a cutout is made inthe platform wall, and a step is inserted through it from the inside.The flange of the step is bonded to the inside of the platform wall. Inthis embodiment, the top bondline is in compression and the bottombondline is in tension (the step is being pushed into the platform).

Both of these embodiments rely on the strength of the adhesive, ratherthan on the structural strength of the components.

The present invention eliminates the weakness of the prior art by havingboth the top and bottom bondlines in compression. As shown in FIG. 4 ,the present invention provides for a specifically designed platformcutout 220 in the sidewall 215 of the platform that the step fits into.The system, generally shown as 200 in FIG. 4 , includes a step 210 thatis specifically designed and configured to lock into the cutout 220(FIG. 5 ). The step includes at least one transition 230 (FIG. 6 ) andat least one notch 240 (FIG. 7 ). The notch and opposite margin aredesigned such that when the step is inserted into the cutout with thebottom of the notch touching the sidewall, the opposite top flange 250(FIG. 8 ) clears the cutout and is moved into the platform by pivotingthe step around the notch. The step transition 230 is designed andconfigured such that the top and bottom flanges fully contact the innerand outer sidewall, respectively. This contact serves to provide moresurface contact area between the step and the sidewall. This designprovides that the upper portion of the flange compresses against theinside of the platform wall and the lower portion of the flangecompresses against the outside of the platform wall, thus causing bothportions to be under compression, rather than tension. Thus, all loadson the step are compressive loads.

Preferably, a second notch 260 is provided on the margin opposite thefirst notch, such that when the step is centered, a portion of thesecond side margin extends over the sidewall, covering it. This coverageprovides for a seal of the cutout. Some platform assemblies that includea platform step are used with insulating liners and other platformassemblies that include a platform step are not used with insulatingliners. According to ANSI A92.2-2015 Section 4.9.5.1, platforms for usewith insulating liners shall not have drain holes or access openings.Therefore the platform step cutout must be sealed if the platform isgoing to be used with an insulating liner. The platform step is fixed toplatforms the same way if the platform is or is not going to be usedwith an insulating liner, therefore the step cutout must always besealed.

To mount the step in the cutout (FIGS. 9A-E), the step is first movedinto place (FIG. 9A). A step notch is inserted into the cutout notch(FIG. 9B). The step is then rotated to completely insert the top flangeinto the cutout (FIG. 9C). The step is centered in the cutout opening(FIG. 9D). The step is then lowered until it locks into place (FIG. 9E).

Different designs and configurations can be used without departing fromthe scope of the invention.

In another embodiment, the invention is thus directed to a step for anelevating platform with a sidewall, the step includes a top flange, abottom flange, and a transition. The top flange and the bottom flangeare joined by the transition; and the step is configured to insert intoa cutout in the platform sidewall. The bottom flange is configured tocontact an outer surface of the platform sidewall when the top flangecontacts an inner surface of the sidewall. In one embodiment, the stepincludes a first step notch in a first side of the transition,configured such that when the first step notch is inserted into a firstcutout notch of the cutout in the platform sidewall, the top flange ofthe platform step is operable to be inserted into the cutout of thesidewall and the platform step is operable to be pivoted via the firststep notch in the first cutout notch such that the top flange contactsthe inner surface of the sidewall. Another embodiment includes a secondstep notch in a second side of the transition; the platform stepoperable to lock into the elevating platform by positioning the topflange such that the top flange contacts the inner surface of thesidewall, positioning the first step notch in the first cutout notch,and positioning the second step notch in a second cutout notch. The topflange is configured such that when the platform step is locked into theplatform sidewall and adhered to the elevating platform with adhesive,the top flange of the platform step covers the cutout, thereby sealingit. The platform step is also configured such that when the platformstep is locked into the platform sidewall, the top flange of theplatform step compresses the inner surface of the sidewall and thebottom flange of the platform step compresses the outer surface of thesidewall, thus providing compressive bonds between the platform step andthe sidewall.

In yet another embodiment, the invention is also directed to anelevating platform with a cutout to receive the top flange of the stepas previously described. The elevating platform includes a first cutoutnotch configured such that when the first step notch is inserted into afirst cutout notch of the cutout, the top flange of the platform step isoperable to be inserted into the cutout of the sidewall and the platformstep is operable to be pivoted via the first step notch in the cutoutnotch such that the top flange contacts an inner surface of thesidewall. The elevating platform and step are operable to lock togetherby positioning the top flange such that the top flange contacts theinner surface of the sidewall, positioning the step notch in the cutoutnotch, and positioning a second step notch in a second cutout notch. Thetop flange and the cutout are configured such that when the platformstep is locked into the elevating platform and adhered to the elevatingplatform with adhesive, the top flange of the platform covers thecutout, thereby sealing it. The platform cutout and platform step areconfigured such that when the platform step is locked into the elevatingplatform, the top flange of the platform step compresses the innersurface of the sidewall and the bottom flange of the platform stepcompresses an outer surface of the sidewall, thus providing compressivebonds between the platform step and the sidewall. In one embodiment, thecutout includes a top cutout portion and a bottom cutout portion,wherein the top cutout portion is wider than the bottom cutout portion;and the platform step includes a first side notch and a second sidenotch. The top flange and the cutout are configured such that when thefirst side notch is in contact with the first sidewall at the bottomcutout portion, the top cutout portion is operable to receive the topflange. Then, the first side notch and the second side notch areoperable to lock into the bottom cutout portion of the cutout, therebylocking the platform step into the elevating platform. The top flangeand the cutout are configured such that when the platform step is lockedinto the elevating platform and adhered to the elevating platform withadhesive, the top flange of the platform step covers the cutout, therebysealing it.

Platform Rib

Currently multiple platform sizes and shapes are manufactured via LightResin Transfer Molding (LRTM) with molded-in ribs or via hand layup withmolded-in ribs. There are several disadvantages associated with thisconstruction. The molded-in ribs necessary to provide structural supportare thick, which adds unnecessary weight to the platform. Quality issuesrelated to molded-in ribs occur because this design is difficult tomanufacture. For example, it is difficult to spray gel coat in a uniformthickness in the mold rib cavity. It is also difficult to consistentlyplace fiberglass in the mold rib cavity. Some molded-in ribs have foamcores, and gel coat cracking can occur more easily in ribs with foamcores when compressive forces are applied such as when platform mountingstuds are tightened.

Furthermore, platforms can't be stacked during shipping due to themolded-in ribs. The rib cavities in the platform mold suffer damagefaster than other areas of the mold. The molded-in ribs are alsorequired to have a slight draft so the platform can be de-molded. It ispreferable if the ribs don't have a draft for mounting purposes.

A minimum of three large objects; plug, master tool, and tool arerequired to manufacture a platform with a single style of molded-inribs. For example, the five different styles of 1-man platformscurrently offered by Altec, Inc. require eight different plugs, mastertools, and tools for a total of 24 large objects. These items take up alot of storage space. They are also more likely to be neglected becausethere are so many of them to keep track of. If the 1-man platform wasmade with pultruded ribs according to the present invention and if itwere consolidated to one platform height then it would only require 1plug, 1 master tool, and 1 tool to produce all of the platform ribstyles currently offered.

The present invention provides for a new elevating platform supportsystem that does not use molded-in ribs, but rather usesexternally-applied reinforcement ribs that address the problemsdescribed previously. The support system is inherently safer thanexisting external rib designs because it uses a mechanical interlockthat prevents the ribs from separating from the platform if the adhesivebetween the platform and ribs fails. A critical feature of themechanical interlock is that part of the rib is inside of the platformand part of the rib is outside of the platform, thus locking the ribinto the platform.

The platform support system, generally described as 300 in FIG. 10 ,includes reinforcement ribs 310 that are fitted into slots 320 in theplatform basket sidewall 215. In a preferred embodiment, the ribs areT-shaped 312 (FIGS. 11A-D). FIG. 11A shows a cross-sectional view of aT-shaped rib according to the present invention.

The example embodiment shown in FIGS. 11A-D was constructed as follows:A 8″×4″×⅜″ Series 500 I-beam manufactured by Strongwell (Bristol, Va.,USA) was cut in half so two “T” shapes existed. The portion of the ribon the interior of the platform was approximately 26″ long. The rib wascut so about 4″ near the bottom of the rib would “hook” onto the outsideof the platform. Two 0.75″ wide slots about 26″ long were cut in theplatform sidewall and the T-shapes were bonded to the inside of theplatform. The rib portion on the exterior of the platform wasapproximately 30″ long.

In another preferred embodiment, the ribs are an off-set double-Lconfiguration 314, shown in cross-sectional view in FIGS. 12A-D. Thislatter configuration is formed by bonding two L-shaped ribs 314 (FIG.12A, units in inches), or by pultrusion or a similar method (FIGS. 12Band C), whereby the thickness of each of the rib sections is varied togive a lighter rib with adequate strength. FIG. 12D shows a double-L ribinstalled in a platform. Perspective views of the ribs of FIG. 12A-D areshown in FIGS. 13A and B.

FIGS. 14A-C show another double-L design rib according to the presentinvention. FIGS. 14A and B show perspective views of the rib only. FIG.14C shows the rib in a transparent platform; the rib on the right ispartially installed and the rib on the left is fully installed. Theexterior “L” shape preferably extends between about 1 and about 13inches beyond the bottom of the slot to provide extra support.

In a preferred embodiment (FIGS. 15 and 16 ), a rib is formed from aT-shaped component 312 combined with an L-shaped component 314. T-shapeand L-shape cross-sections are described as each having an arm and astem. Herein an arm of a letter is defined as a horizontal stroke notconnected on one or both ends and a stem is defined as a primaryvertical stroke (seehttp://typedia.com/learn/only/anatomy-of-a-typeface/ for a descriptionof typeface anatomy).

The T-shaped component 312 is inserted through a slot in the platformwall from the interior of the platform, such that it is extendingoutward, whereupon the stem of the L-shaped component 314 is bonded toit on the exterior of the platform.

In another embodiment (FIGS. 17A-I), the L-shaped component 314 bondedon the exterior of the platform extends below the cutout in the platformwall that accepts the T-shaped component 312 from the inside of theplatform. This extension 316 allows the platform to more effectivelytransfer compressive stress to the L-shaped component near the outsidebottom of the platform. FIGS. 17A-I show various stages of constructionof the embodiment. FIGS. 17A, C, E and G show views wherein the platformis solid. FIGS. 17B, D, F, H and I show views wherein the platform istransparent.

The example embodiment shown in FIGS. 17A-I, 18A-C and 19A-C isconstructed as follows:

An 8″×4″×⅜″ Series 1500 SuperStructural I-beam manufactured by CreativePultrusions (Alum Bank, Pa., USA) is cut in half so two “T” shapesexisted. Two 0.88″ wide slots are cut in the platform sidewall and the Tshapes are bonded to the inside of the platform with a portion of the“T” protruding through the slots in the platform wall. The T-shapedcomponent is 28″ long and the portion that protrudes through theplatform wall is 26.25″ long. This design allows the top and bottom ofthe “T” to completely cover the slot cut in the platform wall to ensurea seal of the cutout. A 3″×3″×0.375″ Series 1500 SuperStructural equalleg angle manufactured by Creative Pultrusions (Alum Bank, Pa., USA) isbonded to the exterior of the platform and to a portion of the T-shapedcomponent that protrudes through the platform wall. The “L” shape isinitially 36.5″ long and is cut to taper near the bottom of theplatform. The “L” shape preferably extends between about 1 and about 13inches beyond the bottom of the slot. The “L” is further trimmed so thatthe portion in contact with the platform is only 2″ wide instead of 3″wide as it is manufactured. In one embodiment, the portion of the “L”that contacts the platform is trimmed even further when required, suchas when the rib is close to the side of the platform and there isn'tenough area to bond a 2″ wide portion. The reduced width providesadequate strength while reducing weight and the amount of adhesiverequired for bonding it to the platform wall. Additionally, a notch 317is cut into the top of the stem of the T at the top of the T-shaped ribcomponent for the following reasons:

Whenever material is removed from a component, for example by cutting aslot in it, the physical strength of that component is decreased by someamount. In an effort to minimize the strength reduction caused by theslots in the platform wall there was a desire to maintain as large of adistance as possible between the top of the slot and the platformflange.

It is desirable for the top of the “T” inside of the platform tocompletely cover the slot cut in the platform wall. In order to achievethis, the portion of the “T” inside of the platform must extend up pastthe slot cut in the platform wall. It is important that the upperportion of the “T” inside of the platform, that covers the top of theslot, doesn't extend up past the beginning of the radius where theplatform wall transitions to the platform flange. This is important tominimize the interference of the portion of the rib inside of theplatform with a platform liner that is inserted into the platform. Someplatforms have mounting holes drilled in their ribs near the top of therib only a few inches below the platform flange. Therefore, it isnecessary for the top of the “T” rib on the outside of the platform tobe no more than approximately 1.5″ from the bottom of the platformflange.

FIGS. 18A-C show the “T” shape utilized in FIG. 17 . In a preferredembodiment, the thickness of the various flat parts of the “T” shape are⅜ inch. FIGS. 19A-C show the “L” shape utilized in FIG. 17 . In apreferred embodiment, the “L” shape flat parts are ⅜ inch thick.

Another example embodiment, shown in FIGS. 20A-C, is similar to theprevious embodiment, with the addition that the rib portion on theexterior of the platform also extends above the interior rib portion atboth ends. In other words, the stem of the “T” extends beyond the arm ofthe “T” at both ends of the rib. In this manner the rib “hooks” ontoboth the top and the bottom exterior of the platform. The dimensions ofthe slot and rib are adjusted so that the exterior portion of the ribfits through the slot when the longer extension end is inserted throughthe slot and moved to its limit.

Another example embodiment has the arm extending vertically beyond thestem of the T at both ends of the rib. One benefit of this design isthat the arm completely covers the slot in the platform wall.

In another embodiment, the T stem is notched at the top of the rib sothat the stem extends vertically beyond the arm while the arm stillcovers the slot near the top of the platform.

Yet another embodiment is for a rib that has a stem that extends abovethe arm at the top of the rib and the arm extends below the stem at thebottom of the rib. This design allows the arm to completely cover theslot in the platform wall while reducing the tendency of the arm toseparate from the platform wall near the top of the rib during loadingscenarios such as “side push” which occurs when the side of a platformis accidentally pushed into a tree.

When the stem of the T-shaped portion extends vertically beyond the armof the T at the top of the rib, this is beneficial during scenarios whena load is being applied to the bottom of the platform (like when theplatform is accidentally slammed into the ground). In this scenario, thestem of the T above the arm of the T on the inside of the platform is incompressive contact with the platform wall and this prevents the arm ofthe T from separating from the inside wall of the platform due to atension force (i.e., the rib being pushed into the platform near the topof the platform).

When the stem of the T-shaped portion extends vertically beyond the armof the T at the bottom of the rib, this is beneficial during scenarioswhen a vertical load is being applied to the inside of the platform(like when an operator is standing in the platform.) In this scenario,the stem of the T below the arm of the T on the inside of the platformis in compressive contact with the platform wall and this prevents thearm of the T from separating from the inside wall of the platform due toa tension force (i.e., the rib being pushed into the platform near thebottom of the platform).

In general, when the stem of the T on the outside of the platformextends above or below the arm of the T on the inside of the platform,the stem is allowed to support more force than would otherwise besupported by the arm or by the adhesive. This occurs because the stemhas a greater section modulus than the arm.

FIGS. 21-26 show the assembly steps of the embodiment of FIG. 17 . Slotsare cut into the platform (FIG. 21 ), whereupon the inner ribs areinserted through the slots (FIG. 22 ). The inner rib is glued to theplatform (FIG. 23 , exterior view; FIG. 24 , interior view). The outerrib is next glued in place (FIG. 25 ). FIG. 26 shows the compressionforces acting on the rib.

In another embodiment, a lanyard anchor bracket reinforcement section325 is attached to rib (FIGS. 27A-C and FIGS. 28A-B). In one embodiment,the lanyard anchor bracket reinforcement section 325 is constructed outof an unreinforced thermoplastic. In exemplary embodiments, the lanyardanchor bracket reinforcement section is constructed of nylon and/orurethane. However, other materials including reinforced thermoplasticsand thermoset are also used for the lanyard bracket. The lanyard anchorbracket reinforcement section ensures connection between the platformmounting bracket and the lanyard anchor bracket even if the platform ribbreaks between these two structures. FIG. 29 shows the embodiment ofFIG. 27 further including a brace 330 to reinforce the lanyard anchorbracket. FIGS. 30A-E show various views of the brace.

FIG. 31 shows a 0.75″ thick urethane bar 335 affixed as a lanyardbracket support.

In yet another embodiment, the present invention is directed aT-and-L-shaped rib including a T-shaped portion that has a T-shapedcross-section with an arm and a stem and an L-shaped portion that has anL-shaped cross-section with an arm and a stem; the arm of the T-shapedportion is positioned inside the elevating platform and contacts aninner surface of the sidewall of the platform; the arm of the L-shapedportion is positioned outside the elevating platform and contacts anouter surface of the sidewall; the stem of the T-shaped portion extendsthrough the sidewall slot and the stem of the L-shaped portion isexternal to the sidewall and extends beyond the top and bottom of thesidewall slot; and the stems of the T-shaped and L-shape portions areadhered to each other. In one embodiment, this rib further including anotch in the top of the rib in the stem of the T-shape portion at theconjunction of the stem and the arm; the notch configured such that thearm and the stem of the T-shape slide over the sidewall via the notch.Preferably, the arm of the T-shaped portion extends vertically beyondthe sidewall slot at both ends when installed in the elevating platformand the L-shaped portion extends between about 1 and about 13 inchesbeyond the bottom of the slot. The rib is preferably formed offiber-reinforced thermosets, unreinforced thermosets, fiber-reinforcedthermoplastics, and/or unreinforced thermoplastics.

Another rib according to the present invention is a double-L-shaped ribincluding a first L-shaped portion and a second L-shaped portion, bothportions having an L-shaped cross-section with an arm and a stem; thearm of the first L-shaped portion contacts an outer surface of thesidewall of the platform and the arm of the second L-shaped portioncontacts an inner surface of the sidewall; the arm of the secondL-shaped portion extends vertically beyond the sidewall slot at bothends; the stem of the second L-shaped portion extends through thesidewall slot and the stem of the second portion is external to thesidewall; and the stems of the portions are adhered to each other or therib is pultruded. In one embodiment, the arm of the second L-shapedportion extends vertically beyond the sidewall slot at both ends wheninstalled in the elevating platform. The rib preferably includes a notchin the top of the rib in the stem of the second L-shaped portion at theconjunction of the stem and the arm; the notch is configured such thatthe second L-shape portion slides over the sidewall via the notch. Inanother embodiment, the stem of the second L-shape portion at the top ofthe rib extends above the sidewall slot. The first L-shaped portionextends between about 1 and about 13 inches beyond the bottom of theslot. The rib is preferably formed of fiber-reinforced thermosets,unreinforced thermosets, fiber-reinforced thermoplastics, and/orunreinforced thermoplastics.

Mount System

The present invention further provides for a mounting plate, system andmethod. Current mounting plates (FIG. 32 ) consist of flat fiberglassplates that have metal reinforcement encapsulated inside of thefiberglass with studs protruding from the fiberglass plate. Thesemounting plates are typically bonded to the exterior of platforms. Whena load is applied to the mounting plate the adhesive at the top is intension and the adhesive at the bottom is in compression. There is agreater potential for a traditional mounting plate to separate from aplatform near the top of the plate where the adhesive is in tension.Other reasons why relying on adhesive as a primary joining mechanism isnot preferred pertain to quality risks such as improper adhesiveapplication, improper adhesive mixing, and improper adhesive mix ratios.

The present invention is directed to a system and method to mountcomponents to a platform wall utilizing a joining mechanism that relieson the structural strength of the platform and the component instead ofadhesive or other fasteners. The attachment method is applicable to anycomponent that needs to be attached to a platform. An example embodimentis a valve mounting plate. The purpose of a valve mounting plate is toprovide a mounting location on a platform wall for a controllerassembly. The controller assembly is used by the operator to direct themovement of the platform while the operator is inside of the platform.

A common feature among the mounting systems of the present invention isthat some portion of the mounting system is located inside and anotherportion is located outside of the platform via an opening in theplatform wall. This is the design feature that allows the mountingsystem to be mechanically locked into a platform wall without adhesive.

Another benefit of the new mounting systems are their reduced size andweight. The reduced size also allows less adhesive to be used due to thereduced bonding surface area that is now allowed due to the redirectionof stress into the platform wall and mounting plate.

Thus the present invention relies on the structural strength of theplatform wall and the mounting plate to hold the two together. Adhesiveis not the primary joining mechanism in this invention.

A first mounting plate example, generally described as 400, is shown inFIG. 33 . This embodiment includes four studs 410 that protrudeperpendicularly through the platform wall. These four studs are used tosecure the controller mounting bracket to the mounting plate. Theembodiment includes exterior reinforcement 415, which is wider at thebottom in order to spread out the compression load. Preferably, thebottom of the external reinforcement is between about 50% and about 100%wider than the top and the ratio of the height to the width of the wideend between about 1.4 and 2.33. Internal reinforcement 420, shown inFIG. 34 , is wider at the top and the ratio of the height to the widthof the wide end between about 1.4 and 2.33, also to spread out thecompression load. Preferably, the top of the internal reinforcement isbetween about 50% and about 100% wider than the bottom. FIGS. 35A and Bshow cross-sectional views of the embodiment. FIG. 35B is amagnification of section A in FIG. 35A. The figures include the studs410, the internal reinforcement 420, the external reinforcement 415,platform sidewall 215. Additionally, a spacer 430 and a dielectric cover435 are included. The spacer is preferably silicone and the dielectriccover is preferably a non-conductive thermoplastic, such aspolycarbonate.

The bottom section 446 includes recesses 449 for stud heads (FIGS. 39C,39E, 39G, 39I, 39J, 39M and 40A-C). In a preferred embodiment, the studs410 are stud fasteners with large, flat heads (large-and-flat-headedstud fastener), such as stud anchor studs (FIGS. 41A-C). Preferably, thestud is formed from a bolt inserted through a large washer and welded tothe washer to form the stud. Designs where the stud is formed by weldinga threaded rod to a flat head, although acceptable, did not provide asmuch strength. The flat sides of the head help to prevent the stud fromtwisting. The heads are preferable perforated and non-circular so thatwhen embedded in composite resin they do not turn when a nut or otherfastener is being applied and tightened. The studs 410 are insertedthrough the holes in the bottom section 447 (FIGS. 42A-C) and themounting plate is rotated into position (FIGS. 43A-F). FIGS. 43A and Bshow a transparent platform with the double- and single-mounting plates,respectively, in position. FIGS. 43C and D show an opaque platform withthe single and double-mounting plate, respectively, in position. FIGS.43E and F are interior views of the platform with double andsingle-mounting plates, respectively.

FIG. 44A-K shows a design that consists of vertically elongatedrectangular reinforcement pieces with rounded corners 450 (the shape isalso called stadium, discorectangle, or obrund) on the inside andoutside of the platform wall. Big head studs penetrate the reinforcementpieces and platform wall and affix the reinforcement pieces to the wall.The elongated rectangular reinforcement pieces are oval in analternative embodiment.

The reinforcement pieces 450 are bonded to the platform wall with anadhesive. The big head stud is inserted through a reinforcement piece onthe inside of the platform, through the platform wall, and through areinforcement on the outside of the platform. A non-conductiveinsulating cap 455 is placed over the stud heads on the inside of theplatform to prevent any current from leaking through the platform wall.The insulating cap 455 is adhesively bonded in place or is connected viamechanical means. For example, the insulating cap is designed so it“snaps” into place over the stud heads when pressure is applied. The topand bottom of the reinforcement sections are rounded to reduce stressconcentrations that is produced by sharp corners. The reinforcementsections on the inside of the platform extend up, past the reinforcementsections on the outside of the platform, by an inch or so. This furtherreduces stress concentrations by transferring more stress into theflange of the platform. All of the same materials proposed for previousdesigns are also used with this design.

The reinforcement sections preferably have a height-to-width ratiobetween about 3 and about 6. Whereas most prior art mounting plates havea height-to-width ratio between approximately 1 and 2, it was discoveredthat a greater height-to-width ratio was needed to prevent separationover time of the plate from the sidewall along the top and/or bottomedges.

In an example embodiment, the width of the plate 450 in FIG. 44A isabout 3.5 inches wide and about 20 inches tall (area=70 square inches).The bolt head shown in FIG. 41 is 2 inches in diameter and the mountingstud is centered in the 3.5-inch-wide portion shown in FIG. 44A. Twoplates with an approximately 8-inch margin above and below the top andbottom bolts do not separate when under a 175 lbs load on a 6.5-inchmoment arm. Thus, the example embodiment was able to support about 95ft-lbs with two of the plates, with a combined area of 140 squareinches, without separation, giving a separation support factor of about0.68 ft-lbs/square inch. In contrast, a prior art mounting plate thatwas rated to support 40 lbs with an 8″ moment arm (26.66 ft-lbs) haddimensions of about 11.5×16 inches (area=184 square inches), giving aseparation support factor of 0.144 ft-lbs/square inch. By increasing theheight to width ratio, the plate is able to withstand several times moreload without separation along the top or bottom edges.

Yet another mounting system example embodiment is shown in FIGS. 45-48 .In this system, slots 505 are created in the platform sidewall (FIG. 45). A plate 510, with at least one upper section 515 and a lower section520 is provided (FIGS. 46A and B). The lower section has a horizontaldimension that is greater than the length of the slot, such that theplatform cannot slide beyond the transition area 525. The lower sectionincludes holes for studs 410. The plate is shown being inserted into aslot 505 in a transparent platform.

On the inside of the platform, two inner reinforcement components 530are positioned between the upper section 515 and the platform. Thereinforcement components are slotted 535 to receive the transition 525(FIGS. 47A-D), so that the two reinforcement components contact oneanother when slid together and provide a reinforcement for the entirearea of the upper section. FIGS. 48A and B show an exterior perspectiveview of the plate rotated into position in a transparent platform. FIGS.49A and B show interior views, respectively, for a plate installed in anopaque platform. FIGS. 49C and D show exterior views, respectively, fora plate installed in an opaque platform.

Advantageously, these valve mounting systems eliminate the riskassociated with using adhesives to mount the mounting plate to theplatform. In particular, a tension force that is created at the top ofthe plate when the plate is loaded has the potential to separate themounting plate from a platform wall. Mechanically interlocking theplatform wall via a slot or cutout in the platform wall eliminates therisk of separation of the mounting plate from the platform wall.However, in some scenarios it is undesirable to cut slots or holes inthe wall of the platform and/or for the platform to include interiorcomponents because a platform liner, used for dielectric insulation, maynot fit in a platform that has extra mounting plate components taking upspace inside of the platform. In these scenarios, it is desirable forthe entirety of the mounting plate to remain on the outside of theplatform.

Such a mounting system according to the present invention includes amounting plate that wraps around the sides of the platform and aroundthe underside of the platform flange. FIGS. 50-52 show a valve mountingplate design, generally described as 600, with side tabs 605 that wraparound the sides of the platform, a top tab 610 that wraps against theunderside of the platform flange, and a main support component 615 thatsubstantially or matingly contacts and is adhered to the planar side ofthe platform. The tabs are non-parallel to the main support component.They are orthogonal to the main support component or at another angleand substantially or matingly contact the sidewall of the platformand/or the top flange of the sidewall. These tabs allow tension stress,which could induce peeling at the outer edges of the mounting plate, tobe transformed into shear stresses. In the preferred embodiment, the topand side edges are tabbed. In an alternative embodiment, only the topedge is tabbed. Surprisingly, this mounting system configurationsupports about four times the load of prior art mounting plates when asimilar moment arm is used. Studs 410 (see FIG. 41 ) are insertedthrough the plate and other components affixed to the platform withthem. FIGS. 51A-D show detailed views of the embedded big-head studs.FIGS. 52A-D show this embodiment mounted on a platform. FIG. 52A is afront view; FIG. 52B is a side view, FIGS. 52C&D are top and bottomperspective views, respectively

The plate is made out of fiber-reinforced thermosets, unreinforcedthermosets, fiber-reinforced thermoplastics, or unreinforcedthermoplastics. The studs are adhesively or mechanically joined with themounting plate. Alternatively, the studs are embedded in the mountingplate when it is manufactured.

FIGS. 53A-C show another embodiment that utilizes edge modifications tochange the tension stress at the edges into shear stress. In thisembodiment the vertical sides are tapered or stepped 620 in order totransition the load to the platform wall more gradually and reducestress concentrations. This design is lighter than the previous designdue to its smaller size and reduced bonding area. This design uses thesame materials and joining techniques as previously described. FIGS.54A-C show the embodiment of FIGS. 53A-C mounted on a platform.

The present invention is thus directed to a mounting plate for anelevating platform. The mounting plate includes an interiorreinforcement piece, an exterior reinforcement piece, and at least onefastener. The interior and exterior reinforcement pieces are verticallyelongated with rounded corners, and positioned on the interior andexterior of the platform sidewall, respectively. The at least onefastener is inserted through the interior reinforcement piece on theinside of the platform, through the sidewall, and through the exteriorreinforcement piece on the outside of the platform. The height-to-widthratio of the reinforcement pieces is between about 3 and about 6. Thefastener is a mounting stud embedded in the interior reinforcementpiece. In one embodiment, the interior reinforcement piece extends abovethe exterior reinforcement piece. In another embodiment, the exteriorreinforcement piece is wider at the bottom than the top; and theinterior reinforcement piece is wider at the top than the bottom. Thebottom of the exterior reinforcement piece is between about 50% andabout 100% wider than the top and the top of the interior reinforcementpiece is between about 50% and about 100% wider than the bottom. Theplate preferably includes a spacer positioned between the exteriorreinforcement piece and the sidewall and a dielectric cover positionedover the interior reinforcement piece and a head of the at least onefastener; the spacer is silicone and the dielectric cover is anon-conductive thermoplastic. The mounting plate is made fromfiber-reinforced thermosets, unreinforced thermosets, fiber-reinforcedthermoplastics, and/or unreinforced thermoplastics.

Another mounting plate according to the present invention includes awide planar section, narrow planar section and a transition. The wideand narrow planar sections are in parallel planes and not coplanar andthe connects the wide and narrow planar sections. The narrow planarsection is inserted through a slot in the sidewall. The wide planarsection has a horizontal dimension that is greater than the length ofthe slot, such that the plate cannot slide through the slot beyond thetransition area. The wide and narrow planar sections are parallel withand juxtaposed to the sidewall, providing a top planar section and abottom planar section. At least one of the planar sections including atleast one hole and at least one fastener, preferably a mounting stud,inserted through the hole to the platform exterior. In one embodiment,the mounting plate includes two inner reinforcement componentspositioned between the top planar section and the platform. Thereinforcement components are slotted to receive the transition, suchthat the two reinforcement components contact one another when inposition and seal the slot. The mounting plate is made fromfiber-reinforced thermosets, unreinforced thermosets, fiber-reinforcedthermoplastics, and/or unreinforced thermoplastics.

The present invention is also directed to a support for mountingcomponents to a container. The support has a front, a back, a bottomedge, at least two side edges, a main support component, a top edge witha tab, and means for attaching components to the main support component,preferably mounting studs embedded in the main support component. Themain support component is substantially parallel to the main planarsurface of a first wall of the container and configured to substantiallycontact the main planar surface of the first wall of the container. Thetab on the top edge is configured to substantially contact theprojection of the container, thereby transforming the tension stressalong the top edge of the mounting plate into shear stress. Preferably,at least one side edge and/or the bottom edge is tapered or stepped. Inone embodiment, the support includes a first side tab along a first sideedge of the support; the first side tab is configured to substantiallycontact the exterior of a second wall of the container that isnon-coplanar with the first wall, thereby transforming the tensionstress to shear stress along the at least one side edge of the support.Another embodiment includes a second side tab along a second side edgeof the support, wherein the second side tab is configured tosubstantially contact the exterior of a third wall of the container thatis non-coplanar with the first and/or second walls; thereby transformingthe tension stress to shear stress along the second side edge of thesupport. In one embodiment, the support is a mounting plate, thecontainer is an elevating platform with sidewalls, a top flange and abottom, and the projection is the top flange. The support is preferablymade from fiber-reinforced thermosets, unreinforced thermosets,fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

In another embodiment, the present invention is directed to an anti-peelstress mounting apparatus. The mounting apparatus includes both aninternal subassembly and an external plate, wherein the internal subassembly includes two internal plates, and wherein the internal plateand the external plate are mounted on opposite sides of a platform wall.

FIG. 55 illustrates an external view of one embodiment of the anti-peelstress mounting apparatus, wherein external plates 5501 are mounted tothe platform wall and wherein the four bolt ends 5503 are operable toattach to an external component. Preferably, the external plates arepositioned with a top of the plate approximately 1 or more inches (2.54or more centimeters) from a lip of the platform wall 5505.Advantageously, the anti-peel stress mounting apparatus reduces cleavagestress between the platform wall and the mounting system when secured toan external component, since the tapered or “stepped” construction ofthe external plate 5501 allows the stress to be redirected into shearstress normal to the plate. The stepped construction further contributesto the reduction of peel stress on the external plate 5501, since amaximum stress is applied along the stepped area, converting the peelstress into shear stress. Preferably, the stepped construction includesa series of rectangular raised thicknesses (layers) that extend awayfrom a mounted surface (e.g., the surface of a platform wall). Thelayers are preferably solid, wherein the plate is constructed as asingle part from uniform material. Each subsequent step of the steppedlayers away from a mounted surface decreases in perimeter size, whereindimensions of each of the rectangular perimeters of the steps aresmaller in each layer further from the mounted surface. This steppedfeature is similar to the tapered and stepped construction illustratedin FIGS. 53A-54C. In another embodiment, the stepped constructionprovides a series of raised thicknesses (layers) that have the shape ofrounded rectangles, squares, ellipses, triangles, or rounded triangles,hexagons, octagons, or any other shape known in the art, including thoseillustrated in FIG. 66 .

FIG. 56A illustrates a cutaway view of the platform with an explodedview of the internal subassembly. The internal subassembly includes twopairs of two plates, wherein each includes a first internal plate 5601and a second internal plate 5603. The first internal plate is preferablyconstructed with injection molded ribs to provide structural support tothe part. The second internal plate 5603 is constructed with a steppedconstruction similar to the external plate illustrated in FIG. 55 . Abolt end is encapsulated on a rear side of the first internal plate 5601and extends within a tubular nub (not visible) from the first internalplate 5601, through the second internal plate 5603, through bored holesin the platform wall, and to a rear face of the external plate. FIG. 56Billustrates a cutaway view of the platform with an exploded view of theanti-peel stress assembly.

In a preferred embodiment, the internal assembly is injection molded asone piece, wherein the first internal plate 5601 is overmolded onto thesecond internal plate 5603. The material of the first internal plate5601 is, in one embodiment, approximately 30% glass by weight withrandomly distributed, short fibers. The second internal plate 5603 ispreferably constructed using fiberglass reinforced polyethyleneterephthalate (PET), which includes long, continuous fibers that areoriented in an alternating 0°/90°/0° pattern, which provides highstrength and stiffness characteristics. The first internal plate, thesecond internal plate, or the external plate are, in one embodiment,constructed from unreinforced thermosets, reinforced thermosets,unreinforced thermoplastics, and/or reinforced thermoplastics. In theovermolded embodiment, it is advantageous for fiber matrices of thefirst internal plate 5601 and the second internal plate 5603 to havecompatible matrices so that the internal subassembly can be injectionovermolded. In an alternative embodiment, the internal plates areconnected by way of an adhesive or welding, including plastic weldingmethods such as induction welding, ultrasonic welding, resistancewelding, laser welding, and friction welding.

The illustrated embodiment includes elongated second internal plates anexternal plates with similar dimensions to previously describedembodiments (e.g., FIGS. 44A-44D). However, in one embodiment, the firstinternal plate is constructed with dimensions that are approximatelyhalf of the dimensions of the second internal plate but with similarlength/width ratios. Further, though two bolt attachment points areprovided per plate subassembly, in a further embodiment, the anti-peelstress attachment apparatus includes three or more connection points perplate subassembly. In one embodiment, the steps of the stepped shape ofboth the second internal plate and the external plate are obliquerelative to the normal axis of the platform wall. Preferably, each stepof the stepped shape is constructed closer to a midline between a firstplate and a second plate. For example, in FIG. 55 , as each step of theexternal plates are constructed further from the platform wall, acentroid of each step's shape is located closer to a vertical midline ofthe platform wall than the previous step.

FIG. 57A illustrates a front view of the external plates 5501. Boredholes 5701 in the external plates 5501 are preferably smaller than theholes bored in the internal plate subassembly. In one embodiment, theholes in the external plates 5501 provide a free running fit for a bolt.In an alternative embodiment, the holes are equal in size to the holesof the internal plates and/or provide a loose-running fit. FIG. 57Billustrates an internal cutaway view of the platform including a frontview of the internal plate subassembly. A first internal plate 5601includes bolt encapsulation areas 5703 that are each constructed tosecure an embedded or integrated bolt, wherein the bolt extends from thefirst internal plate 5601 through a hole in the second internal plate5603. The hole in the second internal plate 5603 is preferably smallerthan a hole of the first internal plate 5601 but larger than a hole ofthe external plate.

In an alternative embodiment, the bolt is secured to an internal plateby any bonding means, such as an adhesive, and is not embedded within aninternal plate. In this embodiment, an insulating cover is operable tobe secured over the bolt by way welding or use of an adhesive.Alternatively, the bolt is reversibly or irreversibly attached to aninternal plate, e.g., via a screw mechanism, latch mechanism, rivetmechanism, or any other mechanical or chemical attachment means known inthe art.

FIGS. 58A, 58B, and 58C illustrate a front view, a perspective view, anda rear view of the first internal plate 5601, respectively. FIG. 58Afurther illustrates an external side of a bolt encapsulation area 5703.Support ribs 5801 on the front of the internal plate are positionedaround the bolt encapsulation area 5801. The perspective view of FIG.58B illustrates the first internal plate 5601 with a hidden view of anencapsulated bolt, which is attached to an inside of the first internalplate 5601. The bolt is encapsulated (e.g., embedded or integrated)within the first internal plate 5601 and is prevented from rotating. Thebolt head consists of multiple holes, which are filled with plasticmaterial during injection molding to secure the bolt to the rest of thebody of the first internal plate 5601. FIG. 58C illustrates an inside ofthe bolt encapsulation area 5703, which extends from the first internalplate 5601 with a thickness equal to the second internal plate 5603 anda diameter equal to the hole 5907 of the second internal plate 5603. Anub 5901 within the bolt encapsulation area 5703 is constructed tosurround part of an encapsulated bolt between the internal platesubassembly and the external plate in order to increase dielectricperformance of the system and reduce the risk of electrical faultoccurrence. The nub 5901 extends from an internal face of the firstinternal plate 5601, through a wall of the platform, and to an internalsurface of the external plate. FIGS. 59A and 59B illustrate a front viewand a rear view, respectively, of the second internal plate 5603.Preferably, an internal diameter of the nub 5901 is slightly smallerthan a diameter of a corresponding aligned hole 6001 on the externalplate 5501, wherein the aligned hole 6001 provides a free running fitfor the bolt. In one embodiment, the bolt head and a non-threadedshoulder of the bolt is encapsulated in the first internal plate 5601,whereupon the rest of the screw is threaded and extends through the nub5901. In an alternative embodiment, the nub 5901 is threaded andconstructed to receive a bolt via a screw mechanism. The second internalplate 5603 preferably includes holes 5907 that are approximately 0.5inches (12.7 millimeters) larger than a bolt head to provide dielectricprotection. The nub 5901 is, in one embodiment, tubular with a circularcross section and conical in construction. In another embodiment, thecross section is any other shape operable to insulate the bolt,including a rectangle (such as a square), ellipse, or triangle, and isconical, pyramidal, cylindrical, or prismatic. In a further embodiment,the bolt contains or is fully constructed from insulating material, suchas a plastic or rubber. In one embodiment, the screw is completelyconstructed from insulating material. In another embodiment, the screwincludes a coating or covering of the insulating material. FIGS. 60A and60B illustrate a front view and a rear view, respectively, of theexternal plate 5501, wherein bored holes on the external plate 5501provide a free running fit for a chosen bolt.

In a preferred embodiment, the second internal plate 5603 and theexternal plate 5501 are constructed with a tapering thickness from rearface of the plate to a front face of the plate. For example, in oneembodiment, the material thickness is greatest on a first step of theplatform-interfacing side of the plate (5905 FIG. 59A, 6005 FIG. 60A),and each of the other steps are less thick than the first (5903 FIG.59A, 6003 FIG. 60A). In one embodiment, the thicknesses of the steps arenon-uniform. For example, in one embodiment, a first step is 0.060inches (1.524 millimeters) thick, and a second and third step are each0.030 inches (0.762 millimeters) thick, resulting in a 0.120 inch (3.048millimeter) total thickness of the stepped portion of the plate. In oneembodiment, a ratio of the thickness of the first layer to at least oneof the subsequent layers is 2:1.

In another embodiment, the nub 5901 of the first internal plate 5601 hasan internal diameter that is at least 0.5 inches (12.7 millimeters)larger than a diameter of a head of a bolt, which provides at least a0.25 inch (6.35 millimeter) clearance distance for dielectricprotection. Similarly, the nub 5901 is at least 0.5 inches (12.7millimeters) larger than an outer diameter of a threaded portion of thebolt. A hole 5907 in the second internal plate 5603 is preferablyconstructed with a diameter equal to a diameter of the boltencapsulation area 5703. The hole 6001 of the external plate is, in oneembodiment, constructed with a diameter operable to accept an end of thebolt and is approximately equal to outer diameter of the threaded bolt.

FIG. 61A illustrates one embodiment of the first internalplate 5601 with encapsulated bolts 5503, which are constructed to extendthrough holes of the second internal plate.

An externalplate 5501 is attached to an outside of the wall 6501. Each of the bolts5503 extend from the first internal plate 5601, through a nub 5901, andthrough the external plate 5501. FIG. 65B illustrates a detailed cutawayside view of the anti-peel stress mounting apparatus attached to theplatform wall.

In an alternative embodiment, a spacer is placed between the exteriorplate and a wall of the platform, wherein the spacer is constructed froma material that provides high dielectric insulation, such as silicone.

In one embodiment, terms such as “insulating,” “dielectric insulation,”“dielectric rating,” and similar terms relating to insulation are notintended to imply that materials are necessarily completely insulatingor non-conductive. Instead, these terms convey a decreased conductivitywithin safe operational boundaries. For example, in one embodiment, theplatform, the platform walls, the doors, the attachment mechanisms, orany other attached pieces are constructed with a dielectric rating of 70kV. Alternatively, the dielectric rating is 50 kV. Preferably, thedielectric rating of 50 kV conforms to ANSI 92.2 Section 5.4.2.5published in 2015, which is hereby incorporated by reference in itsentirety. This standard requires the following test for a dielectricrating of 50 kV: “Platform liners used for insulation shall be tested ina conductive liquid. The liquid level around both the inner and outersurfaces of the liner shall be within 6 inches (152 mm) of the top ofthe liner. The liner shall withstand a minimum of 50 kV ac for 1 minutewithout breakdown through the material.”

Additionally, the platform and associated elements are constructed fromcorrosion and/or impact resistant materials. In one embodiment, thethermoset material and/or thermoplastic material is reinforced orunreinforced.
